I’m not sure about this. Yes, some people say 25x0 is a bad reader while others say it’s acceptable. Are they representing actual hardware difference or the media they tried made all the diverse opinions? Not conclusive currently.

I’ve yet to find a guy who say “I have two 25x0s, one is a good reader while the other is terrible.” or more precisely “I have a disc that one 25x0 reads while the other fails.”.
